Abstract: Streptococcal enzymes are prepd. by fermenting at pH 3.5 and eluting the enzymes, esp. Streptolysin O, hyaluronate-lyase, Streptokinase and streptodornase from the killed cocci with 0.1 M phosphate buffer ato pH 8, then (1) precipitating enzymes with (NH4)2SO4 dissolving the pptn. in 0.02 M phosphate buffer and chromatographing on cross-linked DEAE-agarose and recovering the products by gradient elution, or (2) diluting the culture with an equal vol. of 0.1M phosphate added with stirring at pH 6-7, separating the hyaluronate-lyase from the soln. after adsorption by adding (NH4)2SO4, separating the enzyme by centrifugation, dialysing against 0.02, phosphate buffer and recovering pure from DEAE-agarose, or (3) precipitating pure Streptokinase and Streptodornase by adding 10% NaCl, pptated and Ca3(PO4)2, fractionally precipitating with (NH4)2SO, and chromatographing on DEAE-agarose or (4) adsorbing the enzymes e.g. Streptolysin O, Streptokinase and streptodornase on silica gel used for the recovery of hyaluronate-lyase with water at pH 9.5-10.5, preferably 10, and recovering the pure Streptokinase and Streptodornase as in (3) and by chromatography on DEAE-agarose. Economic process without use of large amounts of precipitants e.g. alcohols and (NH4)2SO4 for isolation of many individual enzymes, rather than one specific one, from the fermentation liquor. The enzymes are used in diagnosis of Streptococci in serum, and for clinical treatment. The killed Streptococci act as centres of crystallisation.

Title: Vehicle chassis alignment checking appts. - uses optical reference system provided by portable projector and graduated screen
Inventor: STAUDINGER ALFONS
IPC: G01B11/26
Filed: 1976-09-20
Abstract: The chassis alignment measurement system for vehicles consists of an optical reference line (34) against which the chassis side members (33) may be gauged. An adjustable projector (22) with horizontal sides arm emits a narrow light beam parallel to the chassis. The projector is mounted on a tripod at one end of the chassis with its arm aligned with the top edge of the chassis member to form one reference point. A graduated screen (28) mounted on a tripod is set up at the other end of the chassis against a similar reference point determined by its horizontal arm, the end of which is aligned with the top edge of the chassis member. The screen is then moved to various positions along the chassis, the horizontal arm ensuring that the correct lateral distance is observed. Any distortion in the chassis member with respect to the reference beam will be indicated by the position of the light spot on the graduated scale.

Title: Broadcast transmission coding system - has card programmed receiver decoding circuits to prevent unauthorised reception
Inventor: GRUBE HANS-JOCHEN
IPC: H04N7/16
Filed: 1976-10-27
Abstract: A radio or TV transmission system prevents unauthorised reception by inclusion of a variable harmonic generator in the transmitter and complementary decoding arrangements in the receivers. Receiver decoders have at least two components, the actual circuits which are build in to the receiver and magnetic cards, punched cards or similar data carriers which can be inserted to program the decoding circuits. The encoding system is suitable for prepayment reception of broadcasts as the decoder programming cards may be distributed through normal retail channels. By varying the encoding of transmissions, for example on a monthly basis, a predetermined reception period can be purchased. Furthermore, for special programmes, such as sporting events, a unique decoding card may be produced.

Title: Screw injection-moulding machine with reciprocating screw - has plunger which pushes the screw towards the injection nozzle
Inventor: JUI-LIEH SU
IPC: B29C45/50
Filed: 1976-11-15
Abstract: Plastics moulding machine has a screw for conveying moulding cpd. from an inlet to an injection nozzle. The screw is adapted to perform a reciprocating movement in addn. to its rotation. A plunger operates so that it pushes the screw towards the injection nozzle. The screw rotates but the plunger does not. The screw is motor-driven via a shaft connection. The plunger is connected with the screw assembly, via bearings and a power transmitting shaft so that it pushes the screw forward, by hydraulic pressure, during the injection moulding step. However, it does not follow the rotary movement of the screw as the latter conveys moulding cpd. to the injection nozzle. Exclusion of the plunger from the rotary movement of the screw minimises wear and tear upon the screw barrel and associated seals. Efficiency of the machine is improved.

Title: Automatic balancing device for vehicle wheels - has flexible oil filled tube containing heavy ball fitted to wheel flange
Inventor: MANDT-RAUCH PETER
IPC: G01M1/36
Filed: 1977-03-17
Abstract: The automatic balancing system for vehicle wheels comprises a circular hollow chamber of glass fibre reinforced polycarbonate next to the rim of the wheel (4). The chamber is filled with a suitable oil (8). The outside diameter of the chamber is matched to the inside dia. of the wheel flange (13). Within the oil-filled chamber is a heavy steel or lead ball (7). The upper shoulder (14) of the hollow chamber is narrower than the remaining part and fits into the profile formed by the wheel flange. When the wheel is rotating, centrifugal force forces the ball against the narrow shoulder to further reinforce the cohesion forces. The balancing device can easily be fitted by hand by merely pressing the narrow profiled upper part of the hollow body into the recess in the wheel flange by sideways and upwards pressure (22).

Title: Nuclear fuel reprocessing by disintegrating and dissolving - using flat dissolving tanks of limited depth with interposed storage tank
Inventor: HUPPERT KARL-LUDWIG DIPL CHEM
IPC: G21C19/42
Filed: 1977-07-19
Abstract: Appts. for dissolving nuclear fuel materials, partic. those from spent, irradiated, disintegrated fuel elements, comprises a flat storage tank (I), into which the fragments are lowered in baskets, and a liq. storage tank (II) for the dissolving liq. partic. HNO3. (I) are ofa safe thickness (in regard to criticality), which is less than that of (II). (I) are fitted against the narrow end faces of (II). which is connected to them by circulating openings. The base of (II) is steeply inclined towards the openings communicating with the bottom of (I), so that any undissolved nuclear fule particles slip down and back into (I) where they are retained. As compared with previous dissolving systems, where the batch limit was about 500 Kg of fuel, the new arrangement enables 1-2 t be processed in a batch. This is made possible by ensuring tht no solid uranium dioxide fuel is allowed to accumulate in the storage tank (I).
